E) none of the above.

Question

Quizplus · Accepted Answer

Double helical DNA:RNA hybrids and double-stranded regions of RNA chains often assume an A-like conformation, which is characterized by a wider and more shallow helical structure compared to the B-form DNA typically found in cells. This conformation allows for the accommodation of the ribose sugar present in RNA.
